    IPC: B01D53/14

    Abstract: 1,3-Diaminocyclohexanes of general formula (I) are suitable for removing carbon dioxide from fluid flows wherein R independently represents C1-4-Alkyl, and n represents a whole number between 0 and 3. The amino groups of 1,3-Diaminocyclohexane are arranged preferably in the trans position relative to one another in relation to the cyclohexane ring level. Absorption agents for removing carbon dioxide from fluid flows contain: a) a 1,3-Diaminocyclohexane of general formula (I); and b) optionally at least one tertiary amine and/or a sterically hindered primary or secondary amine. In a method for removing carbon dioxide from fluid flows, the absorption agent is brought into contact with a fluid flow.

    IPC: B01D53/14

    Abstract: The invention relates to a method for removing acid gases from a fluid flow containing nitrogen oxides, wherein a) the fluid flow is brought in contact with an aqueous absorbent, which contains at least one amino-group-containing compound, in an absorption zone, wherein a deacidified fluid flow is obtained, b) bringing the deacidified fluid flow in contact with an aqueous scrubbing liquid in at least one scrubbing zone and obtaining a deaminated, deacidified fluid flow, wherein the scrubbing liquid is recycled by means of at least one scrubbing zone, c) treating overflow from the at least one scrubbing zone with UV light, and d) combining the UV-treated overflow with the absorbent. The method enables the efficient decomposition of the nitrosamines contained in the absorbent.

    Abstract: Disclosed is an absorbent for removing carbon dioxide from a fluid flow, said absorbent comprising an aqueous solution of: a) an amine of general formula (I), wherein R1, R2 and R3 are selected independently from one another from C1-4-alkyl and C1-4-hydroxyalkyl, R4 in each case is selected independently from hydrogen, C1-4-alkyl and C1-4-hydroxyalkyl, R5 in each case is selected independently from hydrogen, C1-4-alkyl and C1-4-hydroxyalkyl, X stands for OH or NH(CR1R2R3), m stands for 2, 3, 4 or 5, n stands for 2, 3, 4 or 5, and o stands for 0 or 1; and b) at least one activator selected from 5-, 6-, or 7-membered heterocycles with an NH group in the ring and one or to other heteroatoms in the ring, which are selected from nitrogen and oxygen. The absorbent enables a rapid absorption of carbon dioxide from fluid flows.
